RedHat ： 192.168.8.202

AIX: 192.168.8.193

在RedHat服务器上设置NFS服务：

1、RedHat服务器端的设定NFS都是在/etc/exports这个文件中进行设定的，设定格式如下:

[root@redhat /]# vi /etc/exports

[root@redhat backup]# vi /etc/exports

/backup 192.168.8.193(rw,sync,no_root_squash,insecure,no_wdelay,anonuid=501,anongid=503)

启动NFS服务：

[root@redhat backup]# service nfs restart

Shutting down NFS mountd: [ OK ]

Shutting down NFS daemon: [ OK ]

Shutting down NFS quotas: [ OK ]

Shutting down NFS services: [ OK ]

Starting NFS services: [ OK ]

Starting NFS quotas: [ OK ]

Starting NFS daemon: [ OK ]

Starting NFS mountd: [ OK ]

[root@redhat backup]# showmount -e localhost

Export list for localhost:

/backup 192.168.8.194,192.168.8.193

2、在AIX服务器上showmount一下：

bash-3.00# showmount -e 192.168.8.202

export list for 192.168.8.202:

/backup 192.168.8.193

查看nfs_use_reserved_ports的参数值，一般默认是0

bash-3.00#nfso –a |grep use_reserved_ports

如果是0 ，则将nfs_use_reserved_ports参数值设置为1

bash-3.00#nfso –p -o nfs_use_reserved_ports=1

编辑/etc/filesystems:

在/etc/filesystems 添加如下内容

/backup:

dev = /backup

vfs = nfs

nodename = 192.168.8.202

mount = true

options = rw,bg,soft,nointr,rsize=32768,wsize=32768,proto=tcp,vers=3,timeo=600

account = false

在AIX服务器上mount上
